"""Portal-URL resolution for Phase 2b billing errors (nous_billing).

The server emits ``portalUrl`` relative by design (``/billing?topup=open``); the
client must resolve it against the active portal base so deep-links are clickable
on whatever deployment (preview / staging / prod) the user is pointed at.
